A 50-cm-long, 2- mm-diameter electric resistance wire submerged in water is used to determine the boiling heat transfer coefficient in water at 1 atm experimentally. The wire temperature is measured to be 130°C when a Wattmeter indicates the electric power consumed to be 3.8 kW. Using Newton's law of cooling. determine the boiling heat transfer coefficient.
